A rectangular field has the area equal to that of a square field of side 60m.if the breadth of the rectangular field is 32m, fin
V125BC [204]

<u>Given</u> -

  • Area of rectangular field = Area of square field
  • side of square = 60m
  • breadth of the rectangular field = 32m

<u>To find</u> -

  • length of the rectangular field

<u>Solution</u> -

Area of square = side × side = (60 × 60)m² =

Area of square =3600m²

Hence,

Area of rectangular field = Area of square field = 3600m²

Area of rectangular field = l × b = 3600m²

=> l × 32m = 3600m²

=> l = \sf{\frac{3600}{32}\:m}

=> l = 112.5m

so, the length = 112.5m
